The development of advanced lithium batteries represents a major technological challenge for the new century. Understanding the fundamental electrode degradation mechanisms is important for battery performance improvements. The complex electrochemical processes inside a working battery are being explored to a limited extent. Various advanced material characterization techniques have been used to monitor dynamic conditions for optimizing battery materials. State‐of‐the‐art atomic force microscopy methods have been applied to energy storage systems, specifically lithium‐ion batteries. Atomic force microscopy is an ideal tool to provide localized morphological, chemical, and physical information at nanoscale for the in‐depth understanding of the electrochemical processes, reaction mechanisms, and degradation of battery materials. Here, we review recent progress in the development and application of atomic force microscopy for high‐performance lithium‐ion batteries. We discuss atomic force microscopy as an analytical tool to help researchers understand graphite, silicon, layered metal oxides, and other representative electrode materials. We summarize the importance of atomic force microscopy technique in studying the next‐generation Li–S and Li–O2 batteries. We also highlight some of the remaining challenges and possible solutions for future development.

“…Thus, a series of EC‐AFM studies on the influence of the solvent molecule on the SEI morphology and the graphene exfoliation followed. They stated the PC molecule unfavorable properties when operated in a LIB with a graphite negative electrode and that additives can promote the SEI formation . A combined in situ AFM and neutron reflectometry (NR) study revealed a growth of the SEI mainly in a potential range between 0.6 and 0.8 V versus Li/Li + .…”

surface coordination, strain effects, [6][7][8][9] ligand effects, [10,11] ensemble effects, [12] and the electrolyte composition. [13] A detailed understanding of these effects requires experimental and computational procedures to investigate the working mechanisms of the electrocatalysis. Ideally, atomically resolved topographic and chemical information of the catalyst surface under reaction conditions is required. Transmission electron microscopy (TEM) has been reported to be capable of in operando investigation of catalyst structures while catalytic reactions are taking place. [14] However, the instrumentation utilized for such purpose has very strong restrictions and realistic operating conditions cannot be easily applied so far. Alternatively, scanning probe microscopies (SPMs) and electrochemical scanning probe microscopies (EC-SPMs) are able to perform structural measurements of catalytic systems under reaction conditions with resolution down to atomic scales. Normally, EC-SPMs, for instance electrochemical scanning tunneling microscopy (EC-STM), electrochemical atomic force microscopy (EC-AFM), and scanning electrochemical potential microscopy (SECPM), can provide structural information on the solid side of the electrode/electrolyte interface at the atomic level for conductive samples (EC-STM is limited in the case of semi/nonconductive samples). However, these techniques usually lack the capability of chemical sensitivity, ultrahigh resolution reactivity monitoring, and probing the property of the electrolyte side of the interface. One well-developed exception is the scanning electrochemical microscopy (SECM), which will also be discussed in detail within this review. Additionally, SECM and related methods permit gleaning information about the electrolyte side of the electrochemical interface. However, the resolution of SECM and related methods is limited by the size of the SECM-probe and the working principle of SECM.In this review, first a very brief overview on electrocatalysis and on the importance of model substrates for understanding the fundamental underlying principles is given. Thereafter, the operational principle of different SPM techniques is summarized. The main focus of the work lies then on the application of the techniques to study phenomena important for electrocatalysis, including surface topography and adsorption processes. Within that context, also the application of room Improvements toward highly efficient electrochemical energy conversion require a detailed understanding of the underlying electrochemical processes at electrified solid-liquid interfaces. In situ and in operando studies by means of electrochemical scanning probe microscopy (EC-SPM) have become indispensable experimental tools due to their capability of resolving surface topography down to the atomic level even within the harsh environment of electrolytes. EC-SPM methodologies have thus contributed tremendously to the current understanding of electrocatalysis. In this review article, recent achievements in complement...

“…It is shown that during the initial cycle of the LIBs, an interface layer rich with organic/inorganic salts will be formed at the interfaces between the electrodes and the electrolyte [29] . However, commonly used solvent systems such as Ethylene Carbonate (EC), Propylene Carbonate (PC), Ethyl Methyl Carbonate (EMC), Diethyl Carbonate (DEC), etc., as well as the commercial lithium salt LiPF 6 , they decompose at the electrode interfaces and their products are unstable and not dense enough to hinder the contact between the electrolyte and the active materials [30–34] . Moreover, during the long‐term cycle, it will consume a large amount of active Li + and deteriorate the battery performance.…”

A functional electrolyte containing 3,3‐diethylene di‐sulfite (DES) additive is developed to improve the performances of LiNi0.8Co0.1Mn0.1O2 (NCM811)/graphite batteries, especially at high charging cut‐off voltage of 4.50 V. It is indicated that under the conventional conditions of 25 °C and 1 C after 300 cycles in the voltage range of 2.75–4.30 V, the batteries with 0.25 % DES can increase the maximum capacity retention from 66.61 % to 77.25 % initial discharge capacity compared with the batteries without DES. Especially, when the charge cut‐off voltage is increased to 4.50 V, the batteries with 1 % DES exhibit higher capacity retention (82.53 %) after 150 cycles than the batteries without DES (51.19 %). The electrochemical tests and spectroscopic characterization show that this functional DES electrolyte additive well regulates the anode and cathode interfaces with more stabilized films and smaller impedance, which promotes the interfacial extraction and insertion of Li+. In addition, the interfacial film can inhibit the dissolution of the transition metal element Ni from the cathode and protect the structure stability of NCM811 material. The electrolyte containing DES additive reveals promising prospects in the application of NCM811/graphite batteries.
